JAMES ROBERTS, OF NEW YORK, N. Y.

WASH-BOILER FOUNTAIN.

SPECIFICATION forming part of Letters Patent No. 237,699, dated February15, 1881. Application filed April I, 1880. (ModeL) To all whom it mayconcern:

Be it known that I, JAMES ROBERTS, of New York city, in the State of NewYork, a citizen of the United States, have invented certain new anduseful Improvements relating to Wash-Boiler Fountains, sometimes calledTraps, of which the following is a specification.

The invention relates to aclass of washingmachines known as wash-boilerfountains, and will be understood from the following specification andclaims.

I have devised a construction which is peculiarly effective and simple.It is economically made of thin non-corrosive metal, and weighted withan additional mass of cheaper metal secured to the washer in theheatingchamber. This weight serves the functions of anchoring the washerat any point on the bottom of the boiler where the heat may be thegreatest, and retaining and giving off an amount of heat which willincrease and. equalize the temperature of the water as it is thrown fromthe bottom of the boiler to the internal surface of the washer, therebycausing greater expansion and a more rapid circulation of the waterthrough every part of the boiler.

The accompanying drawings form a part of this specification, andrepresent my device.

Figure l is a view of the bottom or lower side of my improved washer.Fig. 2 isa central vertical section of the same. Fig. 3 is a smallersectional view, showing the device applied in a wash-boiler. Figs. 4 and5 are detail views of the collar or coupling.

Similar letters of reference indicate like parts in all the figures.

A is the top, made oblong, as usual. I have made the fountain endrounded and the other square, as viewed in the plan. It may also be maderound, or oblong with rounded ends.

A is an extended rim or deep lip, extending a large part of the wayround, but with a liberal opening at the fountain end to admit waterunder the washer.

B is a shield, curved as shown, standing the whole height of the body AA, and half inclosing the orifice m, through which the water boils upinto the collar A and thence through the tube D, to be pouredout, in theordinary manner, at the top.

A is the expansible collar, having a joint entirely open from top tobottom and lugs at thelower end, which fasten it to the Washer in a wayto throw the top open and cause it to expand inside of the tube and holdthe same firmly upon the Washer. To effect this a lug must be formed oneach side of the open joint, at the lower end of the collar, andfastened securely to the washer, so as to close the joint at this pointand throw it open at the top. One or more other lugs may aid to hold thecollar and washer together.

A heavy weight, Gr, having an extended area, but less depth than thesides A, is mounted fiatwise under the body A, near the end farthestfrom the ascending passage D. It is confined by a screw or rivet, H.

O O are curved deflectors mounted within the structure, and so placed asto receive the entering currents of water and deflect them, as indicatedby short arrows. There is a liberal space, m, between the ends of thedeflectors For shipment, the weight G may be removed by removing thescrew or rivet H, and a quantity of them shipped together, while thelight thin metal structure maybe shipped by itself.

The tubes D are made in two lengths, and should altogether be longenough to discharge the water at a considerable elevation above thesurface of the water in the boiler.

Modifications may be made. I can extend the sides A farther along, so asto approach each other on the curved end of the washer; but I prefer toleave them as shown.

The deflectors O extend the full depth of the sides A, or there may be aconsiderable space above or below or at both places.

By making the weight G in a separate piece from the body, withprovisions for attaching it firmly in the interior of the ease above thebottom, I am able to make it of a cheap material, as lead, which willperform its functions very effectively without coming in contact withthe clothes.

My improved fountain, being much smaller than the bottom of the boilerin which it may be placed, as is plainly shown in Fig. 3, may be movedto different places in the boiler, wherever the heat may be greatest orthe efficacy of the washer most needed, and will always be firmlyanchored by the weight. The weight G, being a solid mass of metal, willbecome intensely heated, and will retain and give 011' this heat in sucha way as to equalize and increase the temperature of the water in thewasher, and this will necessarily increase the expansion and cause amore rapid circulation of the water through every part of the boiler,and at the expense of much less heat from the fire below, as the heatedweight gives off a great amount from above.

Having thus described my invention, I desire to claim-- 1. In awash-boiler fountain, the combination of the deflectors 0, one on eitherside, with a semicircular shield, B, partially encircling them, and withthe casing and tube, substantially as set forth.

2. In combination with the washer formed of thin non-eorrosive metal,the detachable weight G, formed of cheaper metal, and the fasteningdevice H, arranged to serve as and for the purposes herein set forth.

3. In a washer, substantially as described, the combination, with themain body or casing, of the collar A having an open joint its entirelength, and provided with lugs at the lower end on each side of thejointfastened to the top of the washer, drawing the joint together atthis point and throwing it open at the top, adapted to serve with themovable tube D, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand at New York city, NewYork, this 25th day of March, 1880, in the presence of 5 two subseribing witnesses.

JAS. ROBERTS.
